When buyers compare plastic sheets, they often focus on material names first: PET, PP, PS, PVC, PETG. But experienced thermoforming factories know something more important: Sometimes the manufacturing process matters just as much as the resin itself. Two sheets may use similar raw materials, have similar thickness specifications, and even look almost identical in photos. Yet once they enter…

How to find a reliable thermoforming sheet supplier in China? To find a reliable thermoforming sheet supplier in China, focus on these key factors: Material stability (PET, PP, PS, RPET, PETG)Real production capability (not just samples)Quality control and consistencyCustomization flexibilityFactory verification (visit if possible) Suppliers that meet these criteria are more likely to provide…

As CHINAPLAS 2026 approaches, one thing is clear this year:it’s packed. Exhibitor booths were sold out early, and unfortunately, we didn’t secure a spot in time. But here’s the good part: 👉 The exhibition is in Shanghai👉 Our factory is also in Shanghai So instead of meeting us at a booth,we invite you to visit our factory directly. A More Realistic Way to Evaluate a Supplier Let’s be honest…

Let’s just say it upfront: High-PCR PET sounds great on paper. In reality… it’s a bit more complicated. If you’ve been following packaging trends in 2026, you’ve probably noticed one thing—everyone is talking about PCR content. 30%, 50%, even 70%. It’s almost become a badge of honor. But from where we stand—as a thermoforming sheet manufacturer actually running production every day—there are…

✅ Quick Answer PET sheet roll is ideal for automatic thermoforming production with high efficiency, while PET sheet (cut sheets) is better suited for manual forming or small-scale production. The best choice depends on your production method, equipment, and application. What Is the Difference Between PET Sheet Roll and Sheet? PET sheet is available in two main formats: Roll (continuous…

Quick Answer To improve thermoforming results with PET sheet, you need to optimize temperature control, select the correct intrinsic viscosity (IV), ensure uniform heating, use consistent thickness material, and match the mold design to the application. What Does “Improving Forming Results” Mean? Improving forming results refers to achieving: consistent product quality fewer defects stable…

Quick Answer Common defects in thermoforming PET sheet include webbing, bubbles, poor detail, whitening, and uneven thickness. These issues are mainly caused by incorrect temperature, improper IV selection, uneven heating, or poor mold design. What Are Common Thermoforming Defects in PET Sheet? Thermoforming defects refer to visible or structural problems that occur when PET sheet is not…

Introduction Temperature control is the heart of thermoforming. Even the best PET sheet will fail if processed at the wrong temperature. Typical Thermoforming Temperature Range PET TypeTemperatureAPET120°C – 160°CRPET130°C – 165°C Why Temperature Matters 1. Formability Too low: poor forming incomplete shapes Too high: webbing bubbles 2. Material Behavior PET transitions from rigid to…

Introduction If you’ve been sourcing PET sheet for thermoforming, you’ve probably seen the term IV (Intrinsic Viscosity) on datasheets. Many buyers overlook it—but after 15 years in thermoforming materials, I can tell you: IV is one of the most critical factors affecting forming stability, strength, and final product quality. What is IV in PET Sheet? Intrinsic Viscosity (IV) is a measure of…

Direct Answer: Why Plastic Packaging Prices Are Increasing Plastic packaging prices are rising globally in 2026 due to a combination of factors affecting the petrochemical supply chain. The most important drivers include: Rising crude oil and energy prices Geopolitical tensions affecting petrochemical supply Production disruptions in key resin manufacturing regions Increased global demand…

A Decision-Making Guide from 10 Years in Thermoforming Sheet Manufacturing Direct Conclusion (If You Only Read One Section) If your sushi is fresh, chilled (0–8°C), visually driven retail product, choose APET or PET/PE laminated sheet. If your packaging must withstand microwave reheating, high heat sealing temperatures, or hot filling, choose PP sheet. From a production and procurement…

A manufacturer’s perspective from 10+ years of export and thermoforming experience 1. Why double-sided anti-static PET exists (and why single-side often fails) In electronics packaging, static control is not optional, but it is also often misunderstood. Most customers first ask for: “Anti-static PET sheet”What they usually mean is: “A PET sheet that won’t damage ICs during forming, packing,…

Food grade PET sheet rolls are widely used in thermoforming packaging, but long-term consistency remains a key challenge for food packaging processors. This case study documents a 25-ton PET sheet roll shipment to the Netherlands, supplied at 0.6 × 650 mm, used for food-contact thermoforming packaging. The customer has placed six repeat orders, using the same specification, primarily due to…
